ESP32 Forum

Dear all

I'm trying to drive an external ADC via SPI interface using ESP32 Wrover-E
Can I get the code examples for SPI communication via bit banging in ESP32-IDF.
I can't find some example provided to see how it is done

Thanks

Why would you want to bit bang it when esp32 has 2 dedicated spi peripherals?

Because the built-in SPI peripherals are used by a high-bandwidth device that we have to continuously communicate with.
So I need to use bit bang to another SPI device.
I am trying to use an ESP32 connected via SPI to communicate with the ADC127L11 (24bit ADC)

Help is much appreciated.

Kind regards,
